Patented July 28, 1942 UNITED STATES PATENT OFFICE APPLICATOR Willard B.Terry, Salt Lake City, Utah Application April 11, 1940, Serial No.329,178 2 Claims. (01. 12s 2s0) My invention relates to applicators andmore particularly to ointment applicators ofthe type which it is desiredto place in certain definite locations or in spots which are not freelyaccessible, such as deep cuts and which applicator is made and packed ina sanitary sealed container ready for use with the ointment made andpacked preferably in flexible tubes and also carried in said device.

A further object is to provide a sanitary handy, easily operated,applicator which may be carried in the pocket, grip or in suitablecontainers and which will be entirely sealed from handling or othercontact until ready for use.

A still further object is to provide an applicator which has the tubefor placing and dispersing the fluid carried in an enclosed sealed coverand which has the tube containing the medicine also carried in aprotective covering both of which are removed prior to use, but both ofwhich may be again placed on the tube and applicator tube after eachsuccessive use thereof and which applicator tube may be usedindefinitely, the flexible tube containing the material being removed assoon as empty.

These and other objects I accomplish with the device illustrated in theaccompanying drawing in which similar numerals and letters of referenceindicate like parts throughout the several views and as described in thespecification forming a part of this application and pointed out in theappended claims.

In the drawing:

Figure 1 is a longitudinal section of the two covers showing myapplicator tube and a portion of the container tube sectioned.

Figure 2 is a side elevation of the applicator tube, connection, andflexible medicinal container tube.

Figure 3 is a diametrical longitudinal section of a modified type of mydevice.

Figure 4 is an outside elevation of the applicator tube and container ofthe modified type of device.

In the drawing I have shown two different types of my device and inFigures 1 and 2, I have shown a preferred type of applicator, the mainfeature being a flexible tube A filled with the medicine or material tobe applied with one end of the threaded tube at 5 to be screwed into anozzleholding collar 6.

The collar 6 is internally threaded at the one end and is inwardlyflanged at 7 on the other end and the tapered applicator tube or nozzleB is inserted through the collar 6 with a flange or enlarged tapered end8 fitting the flange I of the collar to hold the tapered tube B inplace.

A gasket 9 is placed in the sleeve between the tube B and the threadedend 5 of the flexible tube A to prevent leakage of materials from thetube around the collar.

The collar 6 is externally threaded at l l at the end from which theapplicator tube B extends and a sanitary sealing cap or nozzle cover Cis screwed onto the threads I I to keep the applicator tube B fromexposure. The inner end of the cap or cover C is provided with a gasketl2 to prevent material from passing out of the end of the applicatortube B. I

The flexible tube A is protected by a closed cylindrical body cover Dwhich is screwed onto the externally threaded end l3 of the cover C overthe flexible tube A so that when the two covers are attached togetherthey completely enclose the applicator nozzle and flexible tube fromexterior contact.

The applicator nozzle B may be glass, Bakelite or other suitablematerial which may be sterilized and made sanitary.

In Figures 3 and 4 I have shown a modified type of the device in whichthe covers Cl and DI are identical to those shown in other views but inwhich the collar 6a connecting the nozzle or applicator BI is made inthe form of an elongated body It with a central bore I! of the same sizeas the bore of the nozzle BI and with the end of the body l6 externallythreaded to be screwed into an internally threaded material carryingcylinder l8 in which the medicine is placed and the screwing of thecylinder onto the body [6 forces the material through the bore l1 andnozzle El to any desired place.

To measure the dosage used in this type of device, the elongated body I6of the collar to is externally marked at I9 to show the amount forcedfrom the tube by the relative position of the end of the cylinder l8.

Having thus described my invention, I desire to secure by Letters Patentand claim:

1. An applicator of the class described comprising, a tapered nozzle; athreaded collar into which said nozzle is placed: a flexible tubecarrying a medicament screwed into said collar to provide the medicamentfor distribution through the nozzle; a tapered cover screwed onto thecollarto cover the nozzle; and a cylindrical body screwed onto saidcover to enclose the flexible tube.

2. A device of the class described comprising a flexible ointment tubehaving one end closed and the other end formed into a smaller diameteredthreaded neck; an externally threaded collar screwed onto said neck,said collar having a flange therein; a tapered nozzle having a flangefitting into the flange of the collar and held in place in the collar bythe threaded neck of the tube; a nozzle cover for said nozzle havinginternal threads to fit on the threads on said collarand having-externalthreads at the extreme end; and a cover for said tube having internalthreads; to screw onto the external threads of the nozzle; cover to sealthe nozzle and tube into separate chambers in said covers.

WILLARD B. TERRY.
